Nazi hunters in Chile seeking "Dr Death"

Nazi hunters arrived in Chile on Monday on the trail of Aribert Heim, nicknamed Dr. Death for killing hundreds of inmates at an Austrian concentration camp during World War Two, who they believe may be lurking in picturesque Patagonia.

Heim, who kept the skull of a man he decapitated as a paperweight, is the most wanted Nazi war criminal still thought to be alive. He would be 94 and his family says he died in 1993.

"We are not here thinking that his capture is imminent, but we have to bolster a campaign that we launched a few months ago," Sergio Widder, of the Simon Wiesenthal Centre in Buenos Aires, told Reuters on his arrival in Santiago.
